Hi,
I'm sure there's still people to this day holding them since the beginning some of them might forgot about them and some actually want it to go to 10k+, but jeez you'd need ALOT of patience for that because most of us would think the bubble is gonna pop any time.
There are not many people who could actually be able to hold the coins for such a long time .this is obviously possible in the case of early adopters that have seen all the stages a btc has passed though since the time it was introduced in the market of digital assets. So they know that the selling of Btcs would only provide them disadvantage and if they would keep hold of the coins for a long time then it would definitely earn them huge profits in the end.
Agree with this, there'll always some price pump that distract people from holding their bitcoin for such a long time, 3 years is just too much of a long time and if people who holds that btc don't have that much of faith to bitcoin or in the state of doubtfulness with their investment, a little bit of price pump could lure them to sell all of their assets. That's why only very few of early adopters becoming millionaires right now.
